The Dissipation of Electromagnetic Waves in Plasmas

This anthology includes articles on experimental studies of the interaction of high-power electromag­ netic waves with collisionless plasmas and with electrons. The nonlinear interaction of waves with plasmas has been investigated both under free space conditions and in waveguides. A study of secondary-emission dis­ charges was made in order to ascertain their possible effect on measurements in waveguides. The results presented here on the interaction of high-power waves with plasmas and electrons are of interest to a wide range of physicists and engineers concerned with various questions on the interaction of electromagnetic radiation with plasmas, including microwave heating of plasmas and laser fusion. v CONTENTS An Experimental Investigation of Nonlinear Dissipation of Electromagnetic Waves in Inhomogeneous Collisionless Plasmas - G.
